Mechanical circulatory support as a bridge to definitive surgical repair after post-myocardial infarct ventricular septal defect

Abstract

Ventricular septal defect (VSD) after myocardial infarction (MI) is an uncommon but serious complication. Patients refractory to attempts at medical stabilization and requiring emergency surgery have expected mortality rates greater than 50%. We present three cases of extracorporeal membrane oxygenation bridge to surgical repair in patients with multisystem organ failure who would otherwise require emergent cardiac surgery with associated risk and review the literature for mechanical circulatory support for patients with anterior and posterior post-MI VSD.
